I love having a soap dispenser on the kitchen sink, but the small bottle has to be filled too often and it makes a mess. Can't reach the bottle under the sink and when I poured soap into the top it spilled over. I found several "hacks" on the internet attaching a tube to the dispenser and down under sink to a jug of soap. Google "soap dispenser hack". One on YouTube put a "check valve" on the tubing to keep gravity from pulling soap back down to the jug and having to prime every time you wanted soap. I did the hack using a check valve and it works great, almost instant soap when needed. Thought others might be interested in this too.
